This article talks about how the vast majority of genetic disorders have different effects in different people. It says how one individual carrying certain mutations can develop a disease, whereas another one with the same mutation may not. Why is this? There are many tests and studies that give many different explanations to this question. This article says that the new studies tell us that even if we completelu understand all of the genes important for a particular human disease, we may never be able to predict what will happen to each person from their genome sequence alone. Rather, to develop personalized and predictive medicine it will also be necessary to consider the varying extent to which genes are turned on or off in each person.
It's weird that a disease can effect people differently you would think a disease is a disease and would affect people the same.
